A Chord DHT with 3 bit key address space is shown in Figure 1 below. A Node mapped to key i is denoted by Ni and a data item mapped to ey j is denoted by Kj. There are 3 nodes - NI, N3, NS. The finger table or routing table for node Ni is given in the Figure 1. Key N1+1=2 N1 N142-3 N1.4-5 N3 N3 N5 N5 N3 Figure 1 What is the finger table for N3 ? Suppose a key lookup is done for K4 at N1, explain the search steps through a diagram. [Marks: 4]
